In a class AB amp, the only distortion that can be found is cross over distortion like you say as the signal crosses from positive into negative and visa versa. Other than the class D amps, most receivers I thought were class AB rather than class B. I think your problem is to quite a large extent your speakers.Д¬lick to expand.Thats odd. I would need your boards, as I would need the auto transformers. If you can not build them yourself, I would be prepared to build them for you.

I have attached the circuit you can build to update your speakers and make them a safer load. You other option is to ditch the Klipsch Cornwalls. That unit is of a build quality far above the rest of your system. These amps are of a build quality of your Revox A 77 Mk4. The Quad 909 has no crossover distortion. Performance is determined by the small class A amp. The devices are never stretched and long life can be expected. There are six high current output devices per channel. So you have class A performance without a huge amount of heat. The output dumpers are corrected by a small very high quality class A amp, in a feed forward arrangement. Peter Walker's designs, were guaranteed stable under all loads.ДЄlso these amps are unique in that the output devices can be biased well towards class B. Since these speakers almost certainly present unusual amp loading, I would highly recommend a Quad 909 current dumping amp. With the lowering of margins on newer receivers, I would strongly recommend an external amp. They are effectively four ohm or less in any event, however there are some huge impedance peaks, which allowed them to be rated 8 ohms which they are not. Now the modified crossover makes the speakers rated at a four ohm load. I strongly advise you replace these crossovers before you blow up and more output devices. The auto transformer has to be preserved. However you can build the modified crossovers. The other issue is that the caps used on those speakers are known for severe deterioration over time which compounds the problem.ДЄlso in your speakers there is huge overlap between the mid and HF horn also compounding the problems.ДЄ redesigned crossover was available, but it no longer is. Series crossovers are always tough on amps.

This does not surprise me as are a quasi series design. I understand from descriptions on the NET that the impedance of those speakers is below below four ohms a good deal of the time, and phase angles are well in negative territory. They use an auto transformer, as the horns have to see constant impedance.

At full class A they run hot all the time, even at idle. The more they are biased to class A, the less the crossover distortion and the hotter they run. The more the output devices are biased to class B the greater the crossover distortion and the cooler the devices run. Crossover distortion increases as power output decreases! That is why to me receivers sound pretty dreadful and gritty. The issue is crossover distortion which is hidden in the usual bench tests. The problem is in receivers there is only room for puny devices which can't take the heat of biasing further to class A. Most receivers are biased far too far to class B to be quality units. I think the problem with that Onkyo, is that they have biased it too far to class A to improve audio quality. anyone else have a problem with a 805?Д¬lick to expand.I think your problem is to quite a large extent your speakers. Looking at a Yamaha RX-V2065 that has the same specs as the 805.never again on a Onkyo,all firmware upgrades had to be done ata Onkyo Repair Dealer Only. I looked on Ebay and found 4 other 805's for sale.In Parts.WTF Looks like the 805 had so serious design flaws.

ONKYO TX SR805 PRICE CRACK

I plugged it back in and turned it on again, front display came on then another crack and small stream of black smoke, all in about 2 seconds. 6 months ago the front end display went out.resistors went bad.$185.00 to fix warranty was out.(The repair Tech said there was a note from Onkyo about this problem) thanks Onkyo for not telling us befoore the warranty ran out. I also have alwways had a fan blowing on it as has always run Much warmer then my old 5 year old Yamaha RX-V2400(no HD decoders) that I had to hook back up to my main system. I unplugged it and the right rear was warmer then the rest of the case. and a flash of light from the right rear and a that had a burnt motor smell came out before I could hit the button to turn it off. So I grabbed the remote and turned it back on.Crack. Yesterday it just quit playing a CD in the Blu-ray player. I have really enjoyed this Receiver(Great HD decoders) but now this is the second time in last 6 months it has stopped working.
